Description

Technical Field

[0001] This utility model relates to the field of SMT placement equipment technology, specifically an SMT placement feeding device. Background Technology

[0002] SMT, or Surface Mount Technology, is one of the most popular technologies and processes in the electronics assembly industry. It's a circuit assembly technology that mounts leadless or short-lead surface mount components onto the surface of a printed circuit board or other substrate, and then assembles them using methods such as reflow soldering or dip soldering. In SMT assembly equipment, the PCB board loading device plays a crucial role in the SMT process flow and is one of the key pieces of equipment for production line automation and intelligence. The PCB board loading device is generally a board loading machine. Its working principle is to transport the PCB boards stored in the material frame one by one onto the production line. After all the boards have been transported, the empty material frame needs to be replaced with a turnover box full of PCB boards, and then the PCB boards are transported again, thus realizing the PCB board loading process. However, during the replacement process, PCB board loading cannot be carried out for a short period of time, which affects the PCB board loading speed and reduces its practicality. In addition, during the transportation process, problems such as inaccurate placement may occur, which may lead to damage to the PCB board and incorrect assembly of parts, affecting product quality.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 In this embodiment of the present invention, an SMT chip mounting device includes a support frame 100, a mounting mechanism 200, and two limiting mechanisms 300. A bearing shell 110 is fixedly connected to the top of the support frame 100, and two rectangular holes are provided on the bearing shell 110. Rotating rollers 120 are rotatably connected to both ends of the top of the bearing shell 110, and a conveyor belt 121 is drivenly connected to the outer side of the two rotating rollers 120. A reduction motor 130 is fixedly connected to one inner side wall of the bearing shell 110, and the output end of the reduction motor 130 passes through the side wall of the bearing shell 110 and is fixedly connected to the corresponding rotating roller 120. The mounting mechanism 200 is disposed at one end of the top of the bearing shell 110, and the two limiting mechanisms 300 are disposed on the bearing shell 110 and are opposite to each other.

[0016] Specifically, the feeding mechanism 200 facilitates the transfer of PCB boards onto the conveyor belt 121. By starting the geared motor 130, the corresponding rotating roller 120 is driven to rotate, causing the conveyor belt 121 to rotate, thus facilitating the transport of the PCB boards. Furthermore, the feeding mechanism 200 can limit the positioning of the PCB boards, making it easier to transport them into the pick-and-place machine, ensuring accurate placement and thus guaranteeing processing quality.

[0017] Example 1 like Figure 3-4As shown, in this embodiment, the feeding mechanism 200 includes: two fixed shells 210, two material frames 220, and a connecting shell 230. Both fixed shells 210 are connected to one end of the top of the bearing shell 110. The fixed shells 210 have limiting holes 211 and limiting grooves 212. A push-lock assembly is provided inside the fixed shells 210. Both material frames 220 are slidably inserted into the corresponding limiting holes 211 and limiting grooves 212. Multiple bearing grooves are provided on the material frames 220. The connecting shell 230 is fixedly connected to the tops of the two fixed shells 210. A transfer assembly is provided on the connecting shell 230. The cross-section of the limiting hole 211 is the same as the cross-section of the limiting groove 212, and the cross-section of the material frame 220 is the same as the cross-section of the limiting hole 211. The push-lock assembly includes: a sliding plate 270 and an electric cylinder 280. The sliding plate 270 is connected to the fixed shell 210. The internal sliding connection of the 0 is as follows: multiple push plates 271 are fixedly connected to one side of the sliding plate 270; electric cylinder 280 is fixedly connected to one inner side wall of the fixed shell 210; the output end of electric cylinder 280 is fixedly connected to one side of the sliding plate 270; the transfer assembly includes: stepper motor 240, electric cylinder 250 and vacuum suction cup 260, which are fixedly connected to the connecting shell 230; the output end of stepper motor 240 passes through the side wall of the connecting shell 230 and is fixedly connected to screw 241; screw 241 is rotatably connected to the inside of the connecting shell 230; a moving block 242 is screwed to the outside of screw 241; a rectangular block 243 is fixedly connected to the top of the moving block 242; the rectangular block 243 is slidably connected to the inside of the connecting shell 230; electric cylinder 250 is fixedly connected to the rectangular block 243; and vacuum suction cup 260 is fixedly connected to the output end of electric cylinder 250.

[0018] In this embodiment, multiple slots 221 are used to facilitate the placement of multiple PCB boards. A frame 220 containing multiple PCB boards is inserted into a limiting hole 211, allowing the frame 220 to engage with the corresponding limiting slot 212, thus facilitating the fixation of the frame 220's position. A corresponding electric cylinder 280 is activated, causing it to retract and move the corresponding sliding plate 270 and multiple push plates 271. The moved push plates 271 push the multiple PCB boards on the frame 220, causing a portion of the PCB boards to move out of the corresponding slots 221 without the slots 221 falling off. A stepper motor 240 is activated, driving a screw 241 to rotate, thereby moving the moving block 242, rectangular block 243, electric cylinder 250, and vacuum suction cup 260. When the electric cylinder 250 and vacuum suction cup 260 move to the top of the corresponding PCB board, and the electric cylinder 250 is activated... An electric cylinder 250 is used to move a vacuum suction cup 260, bringing it into contact with the corresponding PCB board. The vacuum suction cup 260 is then connected to an external negative pressure device, creating a negative pressure inside the vacuum suction cup 260. This allows the vacuum suction cup 260 to adhere and fix itself to the PCB board. A stepper motor 240 then moves the electric cylinder 250, the vacuum suction cup 260, and the PCB board, facilitating the removal of the PCB. When the B board is pulled out and the PCB board is moved to the top of the conveyor belt 121, the electric cylinder 250 is activated to extend it and air is supplied to the vacuum suction cup 260, which makes it easier to place the PCB board on the conveyor belt 121. The moving conveyor belt 121 facilitates the transportation of the PCB board, making it more convenient. The material frames 220 on the two fixed shells 210 can be used alternately, so that multiple PCB boards can be continuously transported to the conveyor belt 121, improving the PCB board loading rate.

[0019] Example 2 Based on Example 1, in order to limit the movement of the PCB board and ensure the accuracy of the PCB board's position during transport.

[0020] like Figure 2As shown, in this embodiment, the limiting mechanism 300 includes: a movable plate 310 and a second stepper motor 320. The movable plate 310 is disposed inside the bearing shell 110. One side of the movable plate 310 is slidably connected to a corresponding rectangular hole. The second stepper motor 320 is fixedly connected to the bearing shell 110. The output end of the second stepper motor 320 passes through the side wall of the bearing shell 110 and is fixedly connected to a second screw 321. The second screw 321 is rotatably connected to the inside of the bearing shell 110. A connecting block is screwed onto the second screw 321 and is sleeved and fixedly connected to the movable plate 310. An L-shaped plate 330 is fixedly connected to one side of the movable plate 310, and multiple rollers 331 are rotatably connected to the L-shaped plate 330.

[0021] In practice, by starting the second stepper motor 320, the second stepper motor 320 drives the second screw 321 to rotate, thereby moving the connecting block and the moving plate 310, which in turn moves the L-shaped plate 330 and multiple rollers 331. The two sets of L-shaped plates 330 and multiple rollers 331 facilitate the movement of the PCB board, making the position of the PCB board on the conveyor belt 121 more accurate, which facilitates the use of the pick and place machine and ensures the processing quality.

[0022] In order to facilitate the operation of the utility model by the operator, a PLC controller can be set up, and the geared motor 130, stepper motor 240, electric cylinder 250, electric cylinder 280 and stepper motor 320 are all electrically connected to the PLC controller. The PLC controller is existing technology and will not be described in detail here.
